Figure 7-12. High-magnification view of an inclusion-rich layer (B) between two clearer layers of calcite (A). A lower-magnification view shows the repetition and continuity of these layers. Rafter (1997) concluded that most of these inclusions are gaseous fluid inclusions, and that their development may reflect more rapid precipitation of calcite during dry seasons.
     Photomicrograph was taken in plane-polarized light; field of view is 0.23 mm wide. Anjohibe Cave, Madagascar; Stalagmite MA2; thin section MA2-1. Sample collected by Dr. George A. Brook.
